Bernoulli's principle

Background Research Report What is Bernoulli’s Principle? Who came up with the Bernoulli’s Principle? Bernoulli was the last name of three Swiss mathematicians relatives: Jakob, Johann, and Daniel. “Bernoulli's principle was named for Daniel Bernoulli (1700-1782), a Swiss mathematician”(Martin, “Bernoulli’s Principle”). This mathematician was born on January 29, 1700 in Groningen, the Netherlands. His death occurred on March 17, 1782. During his lifetime, he worked as a professor at the University of Basel in 1733. His principle is all about calculating the flow of fluids. “His Hydrodynamica, published in 1738, is considered his most important work”(Swetz, “ Mathematical Treasure: Daniel Bernoulli’s Hydrodynamica”). This is because his he wrote…

The principle in Venturi piping is based on the Bernoulli’s equation. The different pressure between inside of the venturi meter is created by reducing the cross-sectional area of the flow. This pressure will be converted to energy, as a velocity. We can observe the difference of pressure measured by using a different U-tube manometer (A-D). The pressure difference allows to determine the rate of fluid or discharging flow through the pipe line. Since the inlet venturi is larger than throat…

Introduction Bernoulli principle is a statement of conservation of energy per unit mass for an ideal fluid in steady motion, where it states the sum of pressure, kinetic and potential energies per unit volume is constant (Munson, et al., 2013). Venturi effect is where the pressure of the fluid decreases which causes its velocity to increase as it passes through a constricted section of a pipe. This is the basis of this report’s investigation. The aim of this investigation is to compare the flow…

the appropriate information. “Organization can make the It is very common around the world that many providers always make a mistake when they prescribe drugs. I believe this is occurring again and again due to the design of the system that they are using. Using the principles of usability would prevent such errors in the future. “Usability is one of the most important factor hindering widespread adoption of EMRs”. ( Healthcare Information and Management Systems Society, 2009) The key principles…

The Six Principles of Persuasion. “Persuasion is the act or process of presenting arguments to move, motivate, or change the audience” [1] There are six known principles of persuasion, as follows: 1 – Principle of Reciprocity: is the idea of giving back, being kind, and the same time expecting to cause an effect that will reciprocate the same action back. An example is when a waitress smile a lot, act pleasantly when helping customer, mostly likely she would get a better tip, as a…

Nowadays, Benevolence is not a word used often, or maybe even at all. But there are still examples of what it means to be benevolent every day around us through different people and acts of kindness every day. And yes, even if most people can not spell it, it is still very important to use on a daily basis. However, even if one is benevolent that does not mean it is okay to act in a ‘better than thou’ or in any way all high and mighty in any way. Acting in such a manner is the complete opposite…

Freedom of speech was one of the first major principles written in the constitution. A common misconception of freedom of speech is that it has no limitations, however, when this speech breeds hatred, questions rise about bans and restrictions. When harm becomes involved, the issue of hate speech is often debated. The harm principle is the only purpose for with it is morally legitimate for government or public opinion to interfere with anyone’s liberty of action (including speech) is to prevent…

It seem difficult most of the time to find the best way to succeed in persuading your listeners. The text book offered us with about six principles that are believed to be effective in achieving the goal of successfully persuading our/your listeners which are reciprocity, scarcity, authority, commitment and consistency, consensus and liking. The identification and understanding of where each principle fit environmentally will assist …

4.) The concept of a “harm of deprivation” would be that it means the harm of death, it doesn't harm the person by causing her to be in a bad state, it harms the person by depriving her of bad things. Being dead is not like being in pain, you cant suffer if you’re dead. Death is not an ordinary harm, an ordinary harm for example would be if someone were to break your arm, they harm you because they cause you to be in a certain state: pain. Harm of deprivation means you are depriving someone…

Russian born American science-fiction writer and biochemist once quoted, “Never let your sense of morals get in the way of doing what’s right.” This statement generates a series of controversial questions. What is right? How do morals affect people and society in which we live? Does everyone have specific morals by which they try to live their life? How does someone realize what their morals are? What are morals? These questions cannot be truthfully answered because everyone has their own…
